Strange Tube Location (likely the Fuel line)

I was noticing the other day that back in 2008 the the tube thatís going over the valve cover isnít showing. But now (Mar 2019 - see the two other photos) itís they and it looks way out of place and not very aesthetically pleasing.

Many years ago when I had @65k miles the oil pump failed and it was already out of warranty, I subsequently had the dealership fix it. They said the engine would be tore down quite a bit and while they were in there they recommended to change out parts that get worn over time, valves, springs, etc I agreed and it cost me @$10k for the repair and the engine has run great since - no issues. The odometer currently has 90,300 miles but the engine itself is far younger.

Anyway, my car has just been sitting around for more than a year+ with little to no activity (as I was sick and have been in-n-out of the hospital). So, feeling better now, Iím bringing her back into shape and just now noticed the errant hose location - weird how I never noticed it so many years ago after the repair.

My theory is that the flexible hose (both ends are connected to metal tubes) is a much shorter version than the original and the original hose was connected to the firewall and then fed up to engine under the engine cover.

Any ideas guys?

Yes mine looks the same, pops over the valve cover just like that.

Good to see your doing better.

Fuel Line Leaking

Hi everybody,

I just happened to find this thread after doing a quick search for the name of the hose/line/tube? BradleyJS was referring to, the one circled in the 2nd photo. I own a 2006 530xi wagon (yes, the one with the sunroof leaking issues along with many more) and today after changing my spark plugs and putting the parts back I had taken out earlier I noticed the scent of gas, not very strong but I know it wasn't there earlier. After a brief inspection I discovered that there was a tear or crack in the very same hose/line/tube? in the 2nd photo. I would not call it a leak. It does not drip or ooze or gush fuel but there is fuel present. Started the car up after and no increase in fuel being discharged from the are the area. Burning2nd refers to it as a fuel line which I believe that is what it is, I just wanted to know if it has a prefix or a suffix that could help narrow it down.

1st question is what exactly is the name of the fuel line if not just "fuel line"?

2nd question is can I still drive it or no way gotta fix first?

3rd question is this a easy fix or better off take it in?

4th question is the line pressurized?

Any thoughts would be greatly appreciated.

I have pictures, if anyone wants to see for themselves what I'm talking about. Not sure if I can post them though.

It is just a fuel line. It does have a lock ring where it has the quick connect. Which side of the quick connection is the tear/crack? Are you sure it is leaking from the line and not the quick connection? Did you disconnect the fuel line for any reason? It is pressurized with the battery connected. Once the pump has no power you can relieve the pressure with a small pressure valve on the fuel rail (like a tire valve). I donít think it is safe to work with fuel when the battery is connected. Try to post a picture.

once the car goes to sleep.. it sucks the fuel back down..

When i pulled the manifold, I opened the hood and trunk and waited for the car to go sleep.. after it went to sleep I pulled the negative terminal then i was able to remove the fuel line.. There was no pressure

Thanks for the quick reply! My issue is coming from the right side of the quick disconnect on the hard line.

That's a really good tip. Do you also leave the trunk or rear hatch in my case, up so as to not wake it up when you go to disconnect the negative terminal?

Never mind, I just re-read what you said. I missed the trunk part before. This is easily comparable to trying to get anything done while there is a sleeping baby around.

Realoem.com is your parts friend. That hose is like $100. If it has some problem, just change it. There is a valve on the fuel rail you can operate to release any pressure. It will squirt out some gas, so be prepared for that with a rag.

And no, I did not disconnect or even go near the fuel line while under the hood. Can I use imgur?

Thank you, I did go on Real.oem prior to discovering this but wanted to ask if it had a specific name besides fuel line. Got my answer.

Hmmm...the picture you posted is the hard fuel line feed from the tank. I think that line is metal and the split you see is in the plastic coating over the metal fuel line itself. Now, the seal could be somehow compromised at the quick connect fitting right near there or maybe it's leaking someplace else.

Might he be able to just tear off more of the black cover at the connection to improve where it sits with the quick connect? Disconnect, tear it off, reconnect? Iím not sure how it sits with the cover in place or not. different vehicle but my fuel line from the tank does not have a black cover like that.

I'm not 100% sure but pretty confident the leak is coming from within, underneath, around the quick connect fitting and not somewhere else. Going to disconnect the fuel line within the hour and I'll update when finished. Thank you everyone whose responded so far.

Over due but thankfully resolved update

Well as you can tell I operate on Hawaii time. but better late than never.

I came to the conclusion that the original disconnect was the culprit. Since cutting it off and replacing with a new one the leak is no longer there. The 1st attempt to fix the leak was a questionable move on my husbands part but I did not say anything because I really don't know any better. But I had a hunch that DUCT TAPE was not the answer.

Sure enough the smell of gas was in my face the moment I started the car to leave and pick my son up from school. The duct tape held for one whole day believe it or not. I headed to Napa, bought a new quick disconnect, clamps, etc. Had my husband cut off the old and clamped on the new.

I have a couple concerns, the 1st is losing some slack since we did not add more hose to the repair and used only the remaining hose coming from the rail however what was lost in length is no more than an inch. 2nd concern is only one clamp was used. I was pushing for two but in the end one clamp prevailed. I've been checking it every day a couple times through out the day and so far so good.

I have to thank H.F. for his write up on this problem and providing a list of the parts needed with pictures which is so helpful! And thank you everyone in this thread who responded to my inquiry. I appreciate it very much.

I wouldn't be a true BMW owner if I didn't have another malfunction pop up immediately after my fuel leak so I am off to research how the hell to get the pano sunshades out of the car without stripping it down to the frame. I'm going to have to start a thread because I cannot find my particular dilemma anywhere on the internet and I need someone to ELI5 how to take out the sunshades to recover them (myself) and then reinstall. The verbiage and terms used for each and every part needs it's own dictionary.
